WARNING: Content in post is explicit

Eddie Cibrian's devotion to  maintaining his thick and luscious locks left him lacking in other crucial areas, ex-wife Brandi Glanville charges in her bombshell, no holds barred tell-all,  Drinking & Tweeting, and RadarOnline.com has all the juicy — and explicit — details!.

"Eddie had started taking Propecia, like many men, because he was concerned about hair loss," Glanville writes of The Playboy Club hunk, who famously cheated on the stunning reality star with now wife, LeAnn Rimes. "He had fantastic hair, but who was I to sideline his vanity?"

However, while Brandi admits she appreciated Eddie's proactive self-care, she shares, "This particular drug had nasty side effects - including ones that happened in the bedroom."

Yes, according to the outspoken Real Housewife, the Propecia made Eddie impotent!

"I knew he was concerned about his hairline, but momma needed something h**d. I was not down for a limp d**k and gave him an ultimatum: It was the Propecia or me!" Glanville writes.

So how did Eddie receive the news? Take a wild guess.

"Eddie never took well to being cornered or criticized," Glanville writes. "So it was no surprise when he immediately shot back that my lady business wasn't what it used to be.

"He was actually quite vulgar and said something I don't care to repeat, so pardon my momentary filter. Please enjoy this moment it doesn't happen often."

We'll say!
